The anti LulzSec sweep - conducted in Great Britain, Ireland and Chicago - was facilitated by evidence gathered by none other than Sabu (aka Hector Xavier Monsegur), an FBI informant who acted as the de-facto leader of the hacker cell.

"This is devastating to the organization," an FBI official said at the time. "We're chopping off the head of LulzSec."

Unsurprisingly, LulzSec, or what remains of the hacker group, seems to have other ideas.

"It's ridiculous to believe that by arresting the six prime members of LulzSec that you have stopped us," an electronically voice intoned on the video. "You haven't stopped us. You have merely disrupted the active faction."

Although LulzSec declined to name specific targets, the group vowed to resume attacks against government entities, corporations and agencies.

"As we speak our battle fleet and dormant members are planning some top operations and pranks that will go down in history," the disembodied voice added.
